I am looking for information on the model 8502 high purity change over manifold.
on line specs offer an annunciator, which requires 120 v power.
What is the annunciator? A lignt? A bell? A horn?
I would like to spec a contact closure to be provided in addition to/in lieu of the annunciator.
Remote alarm will be much more beneficial than the annunciator.
What is the electrical connection required.
Does the unit come w/ a plug that can plug into a convenience outlet?
Or does it want to be hard wired into a dedicated circuit?
